USB volume control wheel

thingiverse

Turn up... the volume. This simple project lets you change the system volume on your PC, Mac or even android phone with ease. See it in action Inside are an Adafruit Trinket 5V microcontroller board and a budget-friendly rotary encoder. I spent less than 20€ on this whole project. Parts used: Adafruit Trinket 5V, 8MHz 12mm rotary encoder 4mm M2 screw Micro USB cable Follow these instructions to wire and program the electronics. Don't worry - it's really basic stuff. When everything is wired up, the controller acts as an usb input device that sends out media key commands to your computer. Have fun printing | soldering | turning | listening | muting Post-Printing Wiring and board position exposed Alignment To align the two zylinders perfectly first slide the cap.stl onto the shaft of the rotary encoder. Next apply superglue to the base where the encoder will be placed in the next step. Now slide the zylinders into each other and make sure that the gap between the parts is equal all around. Once the glue dries you're done. Congratulations!
